Sri Lanka’s Tamil minority fought a long civil war for a separate homeland. India, home to millions of ethnic Tamils itself, could not stay fully removed from the conflict. It first armed the very militants it later fought, then paid a devastating price for the reversal. This article covers that full arc, from covert support to a costly peacekeeping mission to an assassination that changed Indian politics.
Must Know
Arming the Militants, Then Brokering Peace
- BackgroundSri Lanka’s civil war grew out of postcolonial policies that marginalised the Tamil minority. Tension exploded into Black July 1983, an anti-Tamil pogrom that killed an estimated 3,000 people, pushing hundreds of thousands of refugees toward Tamil Nadu.
- StoryBetween 1983 and 1987, India covertly trained and armed Tamil militant groups, largely through camps in Tamil Nadu. These included the Liberation Tigers of Tamil Eelam (LTTE).
- DetailThat support wound down only with the Indo-Sri Lanka Accord, signed on 29 July 1987 between Prime Minister Rajiv Gandhi and Sri Lankan President J.R. Jayewardene. It promised devolution of power to Tamil-majority provinces, plus a temporary merger of the Northern and Eastern Provinces, with a referendum on that merger to follow later.
- So whatThe accord led to the Indian Peace Keeping Force (IPKF) deploying to Sri Lanka within days, tasked with enforcing the ceasefire and disarming militant groups.
A Peacekeeping Force Goes to War
- DetailThe LTTE had not been party to the accord’s negotiation and never fully accepted disarmament. The uneasy ceasefire collapsed into open conflict within weeks.
- StoryThe IPKF’s turning point was Operation Pawan, launched 11 October 1987 to take the Jaffna peninsula from the LTTE. An opening commando raid went badly wrong after the LTTE intercepted radio traffic.
- ResultRoughly three weeks of heavy urban fighting followed before the IPKF secured Jaffna.
- ContextIPKF troop strength peaked at roughly 80,000 to 100,000. Fighting a guerrilla force in unfamiliar jungle and urban terrain proved far harder than expected.
Good to Know
A Withdrawal Without Victory
- DetailThe mission cost India dearly: over 1,200 Indian soldiers killed, with roughly 6,000 wounded, across the deployment.
- DetailAfter India’s December 1989 election, Prime Minister V.P. Singh’s government ordered the IPKF’s withdrawal.
- So whatThe last troops left Sri Lanka by March 1990, without having achieved the original disarmament goal.
An Assassination That Changed Indian Politics
- StoryOn 21 May 1991, former Prime Minister Rajiv Gandhi was assassinated at an election rally in Sriperumbudur, Tamil Nadu. The bomber was an LTTE suicide attacker, Kalaivani Rajaratnam, widely known as “Dhanu.”
- DetailThe government’s Jain Commission investigation concluded the LTTE orchestrated the killing in retaliation for the IPKF intervention.
- So whatIt found the group feared a re-elected Rajiv Gandhi might redeploy Indian forces against them. This is a well-documented, direct causal link, not speculation.

Great to Know
A Lasting Caution
- DetailSri Lanka’s civil war continued for nearly two more decades after the IPKF’s withdrawal. It ended only in 2009, when Sri Lankan government forces militarily defeated the LTTE.
- ContextThe war’s final phase drew international criticism over alleged human rights violations by both sides.
- So whatIndia’s IPKF experience, from covertly arming Tamil militants to fighting the same movement directly, is widely cited as a cautionary case. It shaped a far more cautious, diplomacy-first Indian approach to Sri Lanka in the decades since.
Exam Point of View
Exam Point of View
- QuestionUPSC Mains 2022, GS Paper II, Q9 asked candidates to discuss India’s role in Sri Lanka’s recent crisis, framed against the backdrop “India is an age-old friend of Sri Lanka” — the IPKF era is exactly the historical precedent examiners expect you to weigh against India’s more recent, cautious approach.
- WhyObjective questions on this topic often test the exact sequence: covert arming (1983-87) came before the Accord (1987), which came before the IPKF’s deployment, and the withdrawal (1990) came before the assassination (1991). Getting this order right is the main trap.
- WhyDon’t confuse Junagadh or Kashmir-style plebiscite cases with the IPKF mission. The 1987 Accord promised a referendum on the Northern-Eastern Provinces merger, but this was never actually held before the mission collapsed into conflict.
